Digital Coherent Optical Systems Architecture and Algorithms

This textbook details the architecture of a digital coherent optical system and describes its main digital signal processing (DSP) algorithms. The authors first show how the combination of advanced modulation techniques, DSP and coherent detection has led to significant gains in capacity and ease of operation. The authors follow the path of the information from its generation in the transmitter, to propagation through the fiber and processing by the DSP algorithms in the receiver. The work summarizes academic results and presents them in a didactic way to students and practitioners working on the area of optical communications. A full suite of classroom materials is included for easy integration into a curriculum, containing theoretic and simulation problems, and off-the-shelf Matlab/Octave functions.

Darli Mello studied Electrical Engineering at the  University of Campinas (Unicamp), Brazil, where he graduated in 2000. In 2002 he received the M. Sc. degree from the  Munich University of Technology (TUM), Germany. During his master studies he carried out both experimental and theoretical work at the Siemens research labs in Munich. In 2006 he received the Ph.D. degree from Unicamp. After his Ph.D. studies he spent one year with Padtec S/A  as a senior technology engineer. From August 2008 to March 2014 he was with the  the University of Brasilia (UnB) as Assistant Professor. He is now an Assistant Professor at the  School of Electrical and Computer Engineering (FEEC), Unicamp. In 2019 he was a visiting scholar at Stanford University, working on coupled SDM transmission. His main research interests are optical transmission and networking. Darli Mello was TPC member of several conferences, including OFC, ACP, ICC and Globecom. He was the TPC co-chair of SBrT 2011, Imoc 2017 and of the Optical Communications Subcommittee of LAOP 2016. 

Fabio Aparecido Barbosa received the Electrical Engineer degree from the Pontifical Catholic University of Minas Gerais (PUC-Minas),  Brazil, in 2014. In 2017 he received the M. Sc. Degree from the University of Campinas (Unicamp),  Brazil, in the field of coherent optical communications,  working on the performance analysis of digital signal processing algorithms for coherent optical receivers.  He is currently pursuing  the Ph.D. degree at Unicamp, working in collaboration with industrial partners. His main research interests are optical communications and digital signal processing for communications.
